In the United States, installation must conform with local codes

or, in the absence of local codes, with National Fuel Gas Code

ANSI Z223.1-1992, or latest edition available from American

National Standard Institute. Further reference should be

made to the recommendation of your fuel supplier.

NOTE: Any additions, changes, or conversions required in order

for the gas utilization equipment to satisfactorily meet the

application needs must be made by a MIDCO distributor (or

other qualified agency) using factory specified and approved

parts.

In Canada, installation must conform with local codes or, in the

absence of local codes, with Installation Codes for Gas

Burning Appliances and Equipment, CGA Standard

CAN/CGA 1-B-149.1 or 2. Further reference should be made

to the recommendation of your fuel supplier.

INSTALLER: Inform and demonstrate to

the user the correct operation and

maintenance of this gas utilization

equipment. Inform the user of the

hazards of storing flammable liquids and

vapors in the vicinity of this gas

utilization equipment and remove such

hazards. Affix this manual adjacent to

the incinerator burner. CODE

COMPLIANCE IS THE SOLE

RESPONSIBILITY OF THE INSTALLER.

Do not store or use gasoline or other

flammable vapors and liquids in the

vicinity of this or any other appliance.

WHAT TO DO IF YOU SMELL GAS

■ If the incinerator is designed only for No. 4 waste, the level can be lowered to bring the flame to play directly on the smaller loads characteristic of this type of operation. The opening through which the burner fires should be of a diameter only large enough to accommodate the Blast Tube (41⁄4" diameter x 3" minimum long.) Do not allow the Blast Tube to protrude into the incineration chamber. If necessary, build an extension outside of the incinerator wall to increase wall depth.

CAUTION: If the test pressure is over 0.5 PSIG, the test must be made without any burner components connected, including Main and Ignitor Manual Shut-Off Valves. WARNING: Explosion hazard. Do not use oxygen for pressure testing. An explosion could occur during initial start-up. VI ELECTRICAL Installation wiring to the burner must conform to local codes, or, in their absence in the United States the National Electric Code ANSI/NFPA No. 70-1990, or latest edition; in Canada, to CSA standard C22.

■ Check that the electrode ends are positioned and that the gap between the end of each electrode and the ground barrier is spaced per Figure 5. ■ Check that the Ignitor Air Deflector is at the correct angle (45°). See Figure 4. ■ Inspect the electrode wire insulation for cracks or worn areas, or any contact with the burner frame. Dampness will facilitate electrical leakage to ground, which will cause ignition or flame signal failure. SPARK TEST—Main Manual Shut-Off Valve must be off.

Notes: 1. During STANDBY and during RM7890 sequencing the “POWER” LED will blink every four seconds. This is normal. 2. The “ALARM” LED will be lit in the event of any flame failure. 3. To maintain proper operation of this device it MUST be electrically grounded. Refer to Honeywell RM7890 literature for criteria. INITIATE (“POWER” LED is lit). ■ The RM7890 enters the INITIATE sequence when it is powered.

■ The switch mechanism is a bi-metallic disc that snaps over when it is heated to the set temperature. The switch is mounted so that the disc bears against the side plate of the blower housing. ■ Testing the switch to prove that it is functional can be done by removing the ignitor assembly and blowing hot air through the opening toward the blower inlet. If hot air is not available, remove the switch and check for continuity.
